We insisted that all subcontractors tools must be tested before being allowed on site. Most contractors arranged their own testing, and provided copies of their register/records when they arrived on site. A small minority opted for the principal contractor to conduct the test (using the on-site electrical contractors) and recharge for this service.

I agree with Ron. As a CDMC I do get fed up hearing from construction companies that CDM doesn't apply to them as the work they are doing does not require an F10 i.e. non-notifiable. After nearly 20 years of the CDM Regs I would have thought that the message would have got through to small Contractors by now that CDM applies to all construction work.

Provided it is a PC requirement/site rules & forms part of the contract with the sub-contractor, then it can be enforced.

Is it lawful for a PC to require something that is not enforced by law? i.e. portable appliance testing may not be a contractor policy but pre use checks may be. As a PC can I demand a contractor does not use 240 v equipment on site even though he has all the necessary equipment i.e. RCD etc.? and the equipment is used in accordance with all user instructions and HSE guidance?

Chris Absolutely lawful unless they contradict legislation - CDM empowers PCs to make rules as they think fit pursuant to Health Safety and Welfare Rockybalboa I think any contractor stating this needs to consider their level of organisational competence very clearly. It is very clear from the opening of CDM07 that ALL construction is included Bob

"Maybe the original poster of the thread meant non CDM as non notifiable to the HSE. You know under the 30days limit or under the 500 man hours before notifying to the HSE rather than just not working to CDM principles. " Rocky, don't come on here and start trying to be tolerant or understanding. If someone makes such a heinous error as the original poster, then they must be held up to account at the earliest opportunity. No room for error in this business. The letter of the law applies and must be spelt out to all of those ignorami that aren't part of our hallowed brotherhood. it's only a short step from a slip of the keyboard to mass fatalities.
